Embodiment Construction

[0031] Within the scope of the typical embodiments of the device of the invention shown in Figures 1-9, the device is intended for the packaging of liquid cosmetics or pharmaceuticals.

[0032] As shown in Figures 1 and 2, more specifically, the device comprises a container 1 made of elastically deformable shape memory material.

[0033] Therefore, the side wall of the container can be deformed when it is compressed, and it can elastically return to its original shape.

[0034] Said liquid to be released is stored in container 1 . Liquid is introduced into the container through the opening 10 (Fig. 5).

[0035] The container 1 comprises at least two communicating cavities 11 and 12 connected together by two deformable regions 13 and 14 ( FIG. 6 ), which allow to bring these cavities closer to each other by pressing on the outer walls of these cavities, between the two cavities 11 and 12 Channels 15 are provided between them so as to form passages for the liquid contained in ...

Abstract

The invention concerns a device for packaging and delivering a liquid product, comprising a container (1) deformable by pressure applied on its side walls, wherein said liquid to be delivered is stored, said container (1) being closed by a head (2) for dispensing the liquid product which is traversed by an outlet (3) for the liquid product. The device also comprises a liquid drawing tube (4) whereof one end (41) is fixed proximate the outlet (3) for the liquid, the tube being of such length that its other end (42) is proximate the base of the container (1). The wall of the container (1) comprises cavities (5) partly delimiting the outline of the dispensing head (2). The invention is characterized in that at least one passage is provided proximate the dispensing head (2) to ensure an air intake into the container (1) after the liquid is dispensed, so as to allow the container (1) to recover its initial shape by replacing by volume the dose of liquid delivered.

Description

technical field [0001] The present invention relates to devices for packaging and dispensing liquids contained in containers. [0002] More particularly but not exclusively, it relates to a bottle intended to contain cosmetics or pharmaceuticals having a viscosity such that said product can be obtained by pressing, more particularly by compressing, the walls of the bottle. Background technique [0003] Such liquid product dispensers are known and include bottles made of a material sufficiently elastic to return to its original shape after deformation. [0004] The bottle has an opening through which the product is introduced and a feeder tube for the liquid product which is introduced into the bottle and which is secured at one end close to the opening of the bottle. [0005] The bottle also has a cap for sealingly closing the opening so that liquid cannot escape, eg when the bottle is horizontal. [0006] But such devices have the following disadvantages: [0007] - when...
